## AIMS AND CONTENT

### LEARNING OUTCOMES

The aim of the course is to provide the student with an elementary introduction to the concepts and methods of Algebraic Topology.

### AIMS AND LEARNING OUTCOMES

The aim of this teaching is to provide students with a consolidation of the techniques of algebraic topology already learned in the teaching of Geometry 2, in particular through the theory of universal covering. In addition, the teaching aims to introduce new concepts such as the theory of CW-complexes to the theory of homology and cohomology, in particular by using singular homology and higher homotopy groups as examples, All this without neglecting the motivations and historical background on the emergence of these objects. At the end of the course, the student will be able to calculate coverings of a topological space and quotients of a topological space under the action of a group. Establish whether a topological space is a CW-complex and establish a cell subdivision. Finally, the student will be able to calculate the homology and cohomology groups of simple topological spaces and calculate their cohomology ring.

### PREREQUISITES

The teaching is a natural continuation of the teaching of Geometry 2. It is advisable to have taken at least one course in: linear algebra and analytic geometry, general algebra, general topology and an introduction to algebraic topology.
